2 Claims. (Cl. 206-46) r This invention relates to a package of abrasivestrips and more particularly strips useful for such purposes asmanicuring or filing fingernails.

The package of the present invention is char- 510 be; kept intact untilthe supply of strips has been exhausted. Generally stated, the packagecomprises a stock of abrasive strips eachof diminishing width from oneend to the other end thereof, an open frame encompassing the stack atits ,16 edges so that each strip is freely removable from thestackthrough the frame opening, and a band orring encompassing the frametransversely of the stackand slidable from the narrow-end portion tothewide-end portion of the stack to engage and bridge the frame edgesfirmly and thereby to maintain the strips as a stack within the frame.When an abrasive strip is to be removed from the package, it isnecessary only to slide the cross-band or ringto the narrow por- 25 tionofthe stack, as this releases or loosens the frame from the edges of thestrips and hence permits one or more strips to be freely withdrawn fromthe stack. Thereupon, the crossband or ring maybe slid back to thewide-end 30. portion of the stack to reengage the frame firmly againstthe strip edges andto hold the strips together as the desired package.

With the foregoing and other features and objects in view, the presentinvention will now 35 be described in further detail with particularreference to the accompanying drawing, wherein,

Figure 1 shows in perspective a band to constitute the open frame forthe package hereof;

Figure 2 depicts the band after it has been 40 formed up into the frameor holder for the abrasive strips.

Figure 3 shows the frame as it is being filled up with strips in stackedrelationship.

Figure 4 depicts the cross-band or ring for the 45 package hereof.

Figure 5 is a plan view of the package with the cross-band or ring atthe narrow end portion thereof. Figure 6 is a similar view after thecross-band 50 has been moved to the wide-end portion of the package andis thus capable of maintaining the tstackof strips firmly in place.:Figure 7 is a section through the package on the line 1-1 of Figure 6after a few strips have 55 been removed therefrom.

The band It) appearing in Figure 1 may consist of paperboard or paper ofappropriate thickness and stiffness, namely, such as not to buckle atits edges when engaged firmly by the crossband or ring of the packagehereof. A transverse ,5 slit l l maybe cut approximately midway into theband from its opposite longitudinal edges near each of its end edges.The end portions of the band may be interlocked so that the edges ofthe. slit or cut II at one end portion hooks or 10 engages over theintact band portion immediately in line with the slit at the other endportion. By providing a transverse crease or line of score I2 in theband substantially centrally of its end edges, interlocking of the endportions of the band develops the elongated open frame l3 shown inFigure 2. The internal girth of such frame I3 is preferably onlyslightly greater than the total edge length of theabrasive strip to beengaged thereby.

The abrasive strips to be packaged accordant with the present inventionare each shaped to simulate the usual steel finger-nail file. Thus, asillustrated in Figure 3, each strip I4 is of progressively diminishingor tapering width from one end portion to the other, the wide-endportion l4a preferably being rounded at its edges and the narrow-endportion [4b also being shown rounded at its edges but, if desired, beingpointed. In some instances, it may be desirable to create 30, in one ofthe side edges of the strip a curved or arcuate recess corresponding tothe curved or arcuate recess usually occurring in one of the side edgesof the usual steel manicuring file nearits wide-end portion. The strip['4 may be cut from sandpaper, emery cloth, or other suitable abrasivesheet material either or both of whose faces carry bonded theretoabrasive grain of suitable size or fineness.

In forming the package hereof, the strips I4 40 are stacked one abovethe other in the frame 13 as it rests on a table or support until theframe is filled from its bottom to its top edge. The frame assumessubstantially the configuration of the strips, which are of a stiffnessto expand frame and to bridge the frame openings transversely andthereby prevent the abrasive strips from falling out of the frameopenings. The band or ring l5 may be readily and economically made byadhesively securing the end portions l5a of a paper band intooverlapping relationship. It is preferable that the paper of the band l5be of somewhat less thickness and stiffness than that of the frame l3,for this means that such band may be made to encompass firmly thewide-end portion of the frame with little tendency to bend or distortthe upper frame edges unduly even when, as shown in Figure 7, the stripsupply or stack within the frame has been partially exhausted, or whenthe strip supply is largely or completely exhausted.

The band or ring i5 is assembled with the stacked frame by being firstslipped over the narrow-end portion of the frame, as illustrated inFigure 5-, and then being pushed or slid to the wide-end portion of theframe until it engages such latter portion tightly, as shown in Figures6 and 7, and can go no farther without being torn or ruptured. In suchvlatter position, the ring 15- causes the frame l3 to engage frictionallyor hugclosely the edges of the stacked strips and to keep the stripsfrom falling out of the frame. When it is desired to remove an abrasivestrip from the frame 13, the ring I5 is slid to the narrow-end portionof the frame, thereby releasing the frame wall from its tight or closefrictional engagement of the strip edges and enabling a strip to beremoved from the stack most readily in a direction away from thenarrow-end portion of the package, that is, in the direction of thearrow appearing in Figure 5.

When one or more strips have thus been removed from the package, thering I5 may be returned or slid back to its position indicated inFigures 6 and 7 and thus serve to maintain in the desired packaged orassembled condition the remaining strips of the stack.

The package hereof may, if desired, be wrapped in Cellophane, paper, orother suitable wrapping material for shipment and sale. Because of itscompactness and integrity, it lends itself nicely to being carried in apocket or pocketbook. It is to be understood that the package hereof issubject to change or modification while falling within the spirit orscope of the present invention, as defined by the appended claims. Forinstance, it is possible to form up the frame [3 from a paper orpaperboard band whose end portions, rather than being interlocked ashereinb efore described, are adhesively or otherwise secured. Again, theband or ring structure I5 may be of seamless structure and be made ofsuitable flexible material other than paper, for instance, such flexiblesheet or film material as Cellophane or its equivalent. The use ofsuitable paper as the material of construction for the frame l3 and thering l5 has, however, been found to be economical and quite satisfactoryin actual practice.

I claim:

1. A package of abrasive strips comprising a stack of such strips eachof diminishing width from one end portion to the other end portion, anopen frame encompassing said stack of strips at their edges, and a bandencompassing the frame transversely of said stack and'slidable on saidframe from its narrow-end portion to its wide-end portion, said bandbeing engageable firmly with the wide-end frame portion to maintain thestrips as a stack within said frame.

2. A package of abrasive strips comprising a stack of such strips eachof diminishing width from one end portion to the other, a paper bandencompassing said stack of strips at their edges,

each of said strips being freely removable from
